Airline giant easyJet has firmed up the purchase of 135 Airbus A320 family aircraft (100 A320neos and 35 A320ceos).

The initial £13bn agreement was announced earlier in June. The agreement was concluded following a thorough technical and economical evaluation.

John Leahy, Chief Operating Officer-Customers, said: "We are delighted that the easyJet board has now confirmed the order.

"The A320 Family aircraft have the tallest and widest cabin of any single aisle aircraft for added passenger space and comfort. Operationally, the NEO is without doubt the most productive and fuel efficient aircraft available.

"The A320 offers the best productivity, the lowest operating costs, the fastest turnarounds, and best fuel efficiency of any single aisle aircraft in the 180 seat sector."

The order by easyJet sustains nearly 2,500 jobs as well as some 7,500 in the extended supply chain in the UK. easyJet operates one of Europe’s most extensive route networks, and is the UK’s largest airline, carrying 55 million passenger a year.

In addition, easyJet is also the largest A320 Family customer and operator in Europe. The A320 Family is the world’s most successful with over 9,500 ordered and over 5,600 delivered to over 380 customers and operators.
